To all whom 'it concern: I r I Beit known that L ARNOLD NACKE, of the and-county of Philadel hia, State of Pennsylvania, have invente certain new Improvements in Platforms for Bower -Motors, (Case No. 259,) ofwhich the following is a specification.

. My invention relates .to' an' improvement in swinging platforms and has more special reference to platforms for power motors,

---su-'ch ':o instance as gas engines, etc.' In

cases where such power motors are placed in a ,buildin the vibration caused by the oporation 0 this motor-is such as to bar the general employment of same in the upper floors of such buildings. To overcome this mentsxand' features as will hereinafter be more fully described, illustrated inthe drawing, and more particularly pointedout in "the claims following the specification Referring to the drawing :-''-Fi gure 1 is a perspective view; of a platform secured in j accordanciirithixmy inventio'n.-

2 is av partial and 'artial perspective view of. that part ofthe owerportion of the platform which is secured; in accordance 'with ny invefition, to the wall 0f. the build- 1ng.-; r i the platform .as an entirety; B is thelower portion ofsame, or platform proper,

f on which the power motor is adapted to l-est.

C, :C, are uprightssecuring the platform to ,the girders D oftheceiling, while C C are diagonally arranged supporting arms which .emnd from the upper endsof the uprights outer.- edge from the girders 7 wall of the room in which the platform is toithe outer. edgeof the platform B,

said platform is sup orted at its E is the suspended. One side of the lower portion Ii of the platform is in contact and rests form is shown assecured to the wall bv means of the rod H passing through said wall and secured on theother side of the wall by means ,ofthe screws I.

The underlying principle of this my invention resides therein that a swinging platform is secured with the upper part to the ceiling of the room in which it is placed, and

is in contact or rests with part ofthe-lower which it is located. Through this arran e- 'ment thevibrations are taken up by the so id that in the spacein which. said platform was located vibrations were not noticeable. I do not claim here any means of changing the portion against the wall of the space in of substantially the same construction and 3 position of said platform, as such adjustable means are shown and claimed in application,

Serial No. 252,058, filed March 25th, 1905,.

' Having now described my invention, what I claim as new anddesire to secure by Letters Patent is V 1 1. A platform for heavy machinery adapt a ed to bearranged adjacent to the floor 0 ,room, in, combination with hangers by which said. platform is supported from the joists or girders of a floor above, said hangers being connected to said joists or girders adjacent to the point of'support of the joists or girders .in the wall of the building, and means in the plane of the platform for anchoring the latter to said wall, whereby the transmission of vibration of the machincry to the floor adjacent to which it is placed is prevented, the transmission of such vibration .to the floor above being minimized by absorption of the vibration by the hangers and by the attachment thereof near the wall.

2. A platform for heavy machinery adapted to be arranged adjacent to the floor of a room, in combination with hangersby which said platform is supportedfrom the joists or girders ofa floor above, said hangers being connected to said joists or girders adjacent .to the point of support of the joists or girders in the wall of the building, a rod in the plane of the platform and adapted to be passed through the wall for anchoring the platform to said wall, and means'carried by said rod for holding the same in engagement with the wall, whereby'the transmission of vibration of the machinery to the 'fioor adjacent to which it is laced is prevented, the witnesses, this twenty-sixth day of May tiginsngssion of such (iribration to the i10121 A. D.\1905. v v

a ove ein minimize by a sorption 0 t e vibration'fiy the'hangers and by the attach- ARNOLD NACKE" 5 ment thereof near the wall. Witnesses: mm
